April 19, 1775, marked the first battle of the American Revolution. On that day, 700 British soldiers marched from Boston to Concord to seize a stockpile of military arms and supplies. The expedition caused patriot leaders to raise the alarm and muster the militia. The scale of the response is truly staggering and hints at a surprising amount of organization.
In 1774, a war between England and Massachusetts Bay Colony appeared inevitable. In preparation, Massachusetts militiamen relied upon muskets obtained from various sources: inheritance, the French and Indian War, the Siege of Louisbourg, and commercial markets.
The result was a variety of weapons of different caliber, origins, and values.
